Title: Vehicle with backup mode for four wheel steering
Inventor: ROSS-MARTIN TORQUIL
IPC: B62D5/00
Filed: 2007-04-20
Abstract: An automatically controlled vehicle, for example for use in a personal rapid transit system, comprises front and rear wheels 2, 4 which are steerable by means of steering actuators 16, 18. In normal operation, a coupling 20 is disengaged, so that the front and rear wheels 2, 4 are steered independently of each other. In the event of failure of one of the steering actuators 16, 18, the coupling 20 is engaged, and both front and rear wheels 2, 4 are steered, for example in opposite directions from each other, by means of the remaining functional steering actuator. The steering actuators 16, 18 are typically electric motors. In one embodiment, a rear steering actuator 18 is shifted in order to disconnect a clutch (46 see fig 3) and to connect the rear actuator 18 to the front actuator 16 via the coupling 20. In another embodiment, the coupling is provided by closing a vent valve 44 to allow linking between front and rear hydraulic cylinders (34, 36 see fig 2).

Title: MWD Mud Pulse Telemetry Reflection Cancellation
Inventor: AIELLO ROBERT ANTHONY
IPC: E21B47/18
Filed: 2008-01-23
Abstract: Method and apparatus for optimizing mud pulse telemetry data rate by processing a sequence of measured pulses to minimize adverse effects of pressure pulse reflections, attenuations and distortions. A downhole telemetry unit cooperating with a sensor and disposed in a MWD or LWD logging tool generates a sequence of pulse within the mud column. The sequence is encoded to represent the response of the sensor disposed within the logging tool. The encoded pulse sequence is sensed at the surface of the earth using a pressure transducer. The output of the transducer yields an electrical signal that is typically attenuated and can contain reflections and distortions. The signal is transformed from the time domain into the frequency domain, combined with measured parameters representing delay time of a reflect, distortion or a multiplier. The resultant original signal is transformed back into the time domain and de-modulated to obtain information about parameters of interest.

Title: Method for determining physical properties of structures
Inventor: LU XINYOU
IPC: G01V3/12
Filed: 2007-06-13
Abstract: Method for efficient inversion of controlled-source electromagnetic survey data to obtain a resistivity model of the subsurface of the survey area. The method extracts the dimensions and location of sub-surface structures as they may be revealed by existing seismic or other available high resolution survey data from the subsurface area (33). This structure geometry information is used to construct a discretization (grid, or mesh) for the inversion computation (34) that is different from the mesh used for the forward modeling calculations (32) in that (a) it has fewer and hence larger cells; and (b) the cells honor the assumed structural information. The inversion need only extract resistivity information (35), the geometry of the resistive structures being specified by the inversion mesh.

Filed: 2009-03-24
Abstract: Apparatus for cutting a multiplicity of wafers from a block comprises means to form a flat closely spaced parallel array of wires 11, and means to move the block 14 through the array, or vice versa. The apparatus also includes means 15 to apply abrasive slurry to the array before it reaches the block, in which there is provision to limit the length of wire along which there is a full supply of abrasive slurry during the start up of the cutting process into the block. The provision may comprise a cylinder shaped piece of softer material 21, which is rotatable between subsequent sawing runs. Alternatively, a separate tube or strip of softer material (23, fig 3) may be attached to the block by glue, so that the array of wires initially cuts into the softer material with little or no slurry; or a brush or scraper (26, fig 6) may be arranged to remove slurry from the array of wires. The supply of abrasive slurry to the block prior to starting the main cutting process may be reduced or eliminated. The apparatus is aimed at preventing the wires of the array from combining and so giving rise to local area thickness fluctuations.

Title: Proximity sensor for detecting an attempt to disable a monitoring tag or portable GPS tracking device
Inventor: ANDERSON JOHN
IPC: G01S1/00
Filed: 2009-09-01
Abstract: A proximity sensor is provided for use with a monitoring tag or portable tracking device worn by an individual, whereby the tag or device relies on GPS or RF signals for location detection. The proximity sensor can determine if signals used by the monitoring tag or portable tracking device are being deliberately blocked by an object, such as by metal foil being placed in proximity to the tag or device. The proximity sensor includes an oscillator 2, a directional coupler 4, and a stub antenna 8. When GPS or RF signals are lost, the proximity sensor is turned on, and the oscillator 2 provides a transmit signal to the stub antenna 8 via ports 6a and 6b of the directional coupler 4. A third port 6c of the directional coupler 4 acts as a coupled port when RF power that has been transmitted by the antenna 8 is reflected back to the antenna by a blocking object. A detector provides an alert if the magnitude of the transmit signal that is reflected back to the antenna 8 in the form of a receive signal exceeds a set threshold.

Title: Improvements in vinyl resins
IPC: C08F8/28
Filed: 1936-04-07
Abstract: Relates to production of substantially colourless polyvinyl acetal resins from interpolymers of one or more vinyl esters of low molecular weight (e.g. vinyl acetate, propionate, or butyrate) with up to 15 per cent of a vinyl ester of high molecular weight (e.g. vinyl oleate or stearate) or with up to 40 per cent of an acrylic ester or a vinyl halide.  Esters of low and high molecular weight are defined as those in which the acid radical contains up to 4, or from 6 to 22, carbon atoms respectively.  The polymers are hydrolyzed and simultaneously or subsequently condensed with one or more saturated aliphatic aldehydes in the presence of a catalyst, an organic solvent (which may or may not include alcohol), and water (or water and alcohol) in amount such that homogeneous reaction conditions are maintained when 80 or more per cent of the hydroxyl groups formed are acetalized, but large enough to give a colourless product By employing mild hydrolysis conditions, the product may include a substantial proportion of vinyl ester groups of high molecular weight or of acrylic ester or vinyl halide groups and have an improved water resistance.  In examples: (1) an interpolymer of vinyl acetate and stearate is treated with paraformaldehyde in solution in ethyl acetate, ethyl alcohol, water, and sulphuric acid to give a product containing stearyl, acetyl, methylal and hydroxy groups; (2) an interpolymer of vinyl acetate and oleate is treated with paraldehyde, propionaldehyde, or butyraldehyde as in example 1, to give a product containing oleyl, acetyl, acetal and hydroxy groups; (3) an interpolymer of vinyl acetate and methyl acrylate is treated with formalin in solution in acetic and sulphuric acids to give a product containing methyl ester, acetyl, methylal, and hydroxyl groups Specifications 396,186, 436,072, 454,691, and 466,598 are referred to.
